Siemens 6SN1118-0NH01-0AA0 – SIMODRIVE 611 Universal HR – 2-Axis Closed-Loop Control Unit

Technical Description

The Siemens 6SN1118-0NH01-0AA0 is a SIMODRIVE 611 Universal HR axis control module designed for 2-axis closed-loop control in high-performance CNC applications.
It supports incremental SIN/COS 1 Vpp encoders and absolute EnDat encoders, making it suitable for precise speed, position and torque control in advanced machine tools.

Thanks to its HR (High Resolution) regulation architecture, the module delivers excellent axis control quality, high dynamics and stable behaviour even in demanding industrial cycles.
Its torque and speed setpoint generation functions ensure accurate drive control and optimal performance.

The 6SN1118-0NH01-0AA0 can be expanded with Siemens option modules to adapt to a wide range of SINUMERIK and SIMODRIVE systems.
